Definitions
- the present invention relates to components of a construction machinery loader, and in particular to a loader high unloading device that can greatly increase the unloading height and unloading distance of a loader. Background technique
- the currently used loader unloading working devices in order to increase the unloading height and unloading distance, generally adopt two methods: One is to lengthen the ordinary loading motor arm, that is, to lengthen the boom to increase unloading. Height, although this method is simple, the lengthening of the boom reduces the lifting capacity of the loader, so this method is at the expense of the loader ’s power performance index and the bucket ’s loading capacity.
- the limitation is that it can only increase the unloading height by a small amount, and it can not completely meet the current requirements for higher and higher unloading heights and heavy lifting weights; the other is to modify the two-port valve on the basis of the two-port valve ordinary loader.
- the object of the present invention is to provide a high-loading device for a loader, which can overcome the shortcomings of various existing unloading working devices, and add a series of loaders with a high unloading height, a large unloading distance, and a low cost.
- Another object of the present invention is to provide a high-loading device of a loader, which can make The high dump bucket is turned over and retracted according to the predetermined requirements to avoid misoperation of the high dump bucket.
- a loader high-unloading device includes a high-unloading bucket, a bracket, and a boom. Both ends of the bracket are pivotally connected to the boom and the high-unloading bucket.
- the device further includes a large connecting rod. One end is pivotally connected to the high unloading bucket, and the other end is pivotally connected to a small link, and the other end is pivotally connected to the bracket; a locking element is arranged on the upper portion of the bracket, and a locked position is provided at the corresponding position on the high unloading bucket. The element is locked or opened by the locking element and the locked element, so that the high dump bucket and the bracket form a rigid connection or relative rotation; a small link limiting element is provided on the movable arm.
- the advantages of the invention are: without lengthening the loading arm and reducing the dynamic performance index of the loader, there is no need to increase the high-unloading auxiliary hydraulic system and operating mechanism, and only the tie rods and buckets are replaced, that is, the current two-valve ordinary loader (Such as ZL30-ZL50)
